Unbound and hydraulically bound mixtures - Test methods for laboratory reference density and water content. Introduction, general requirements and sampling Ingestion-build-207047 BS EN 12503-4 specifies performance1 Scope This European Standard specifies a number of test methods for the determination of the relationship between the water content and the density of unbound and hydraulically bound mixtures under specified test conditions. The test results provide an estimate of the mixture density that can be achieved on construction sites and provides a reference parameter for assessing the density of the compacted layer of the mixture. The test results are used
